Description

Technical Field

[0001] The utility model relates to the field of feed screening and weighing, in particular to a feed screening and weighing device. Background Art

[0002] Before packaging chicken and duck feed, the feed particles in the same package are often the same size, which requires the produced chicken and duck feed particles to be screened and weighed. At present, feed screening uses multiple layers of screens with different apertures to shake back and forth for screening, or uses multiple drums with circular holes to roll inside and outside for screening. During the screening process, due to the large-scale dynamic effect, it is often easy to cause the feed particles to break. Sometimes multiple particles accumulate or block the screen holes, resulting in poor screening effect. In addition, the screening device used can only screen feed particles in one state, and cannot effectively screen round rod-shaped particles. Utility Model Content
